Babies are fed milk alone because milk is a complete food that contains proteins, fats and carbohydrates.
The sugar that occurs naturally in milk is called LACTOSE; it consists of one galactose molecule and one glucose molecule.
As a result, dairy food intake must be greatly limited or – better yet – eliminated during a low-carb diet.
Non-fat milk and yogurt contain no fat, but just as much sugar (lactose) as whole milk and yogurt.
